Emperor Filter Owner's Manual (pdf file in new window)
The Marineland Emperor 400 Bio-Wheel Power Filter powerfully cleans your aquarium water through mechanical, chemical, and biological filtration mechanisms to remove debris, water impurities, and dangerous toxins. This hang-on power filter contains a built-in 400 gph pump that runs water across the Bio-Wheel for biological filtration, through the Rite-Size filter cartridge for mechanical filtration and through the Black Diamond Premium Activated Carbon for chemical filtration (removing odors, discoloration and impurities).
